Description of key information

The biodegradability of Hexa-1,5-diene has been predicted via the Ready Biodegradability model (IRFMN) (version 1.0.9) QSAR within the VEGA software (version 1.1.4) and the BIOWIN (version 4.10) QSAR within the EpiSuite software (version 4.11). Both QSAR models fulfil the OECD principles for QSAR model validation and the substance falls within the applicability domain of the models. As such, the prediction results are considered adequate for addressing the biodegradation data requirement.

Hexa-1,5-diene was predicted to be readily biodegradable according to the BIOWIN (v. 4.10) QSAR and potentially readily biodegradable according to the Ready Biodegradability model (IRFMN) (v. 1.0.9) QSAR. As such, it is concluded that Hexa-1,5-diene is readily biodegradable.
